Refrigeration is the process of moving heat from one location to another by use of refrigerant in a closed cycle. Oil management; gas and liquid separation; subcooling, superheating, and piping of refrigerant liquid and gas; and two-phase flow are all part of refrigeration. Applications include air conditioning, commercial refrigeration, and industrial refrigeration.
A successful refrigeration system depends on good piping design and an understanding of the required accessories. This chapter covers the fundamentals of piping and accessories in halocarbon refrigerant systems. Hydrocarbon refrigerant pipe friction data can befound in petroleum industry handbooks. Use the refrigerant proper-ties and information in Chapters 3, 29, and 30 of the 2009
